Political Developments after 1979

The Islamic Republic’s constitutional structure combines elected institutions with religious leadership and supervisory bodies. In the consolidated constitution incorporating the 1989 amendments, the president heads the executive except in matters assigned directly to the Leader. The Leader holds supreme military command and important appointment powers. The Guardian Council reviews legislation for compatibility with Islam and the constitution and supervises specified elections. These provisions establish formal authority; they do not measure how independently institutions operate in practice. s1

This distinction helps explain why a presidential election cannot, by itself, describe the distribution of power across the state. It also guards against treating constitutional promises as proof of their implementation. s1

The Green Movement developed after the disputed presidential election of 2009. Later demonstrations had different immediate triggers: protests beginning in Mashhad in December 2017 focused initially on economic conditions, while the November 2019 protests followed a fuel-price increase. These episodes should not be flattened into one continuous movement with identical participants or demands. Their differing starting points show how disputes over representation and material conditions could both become confrontations with political authority. s2s3

In 2022, the death of Mahsa Jina Amini following her detention by the morality police triggered the Woman, Life, Freedom protests. An Associated Press account of the UN fact-finding mission’s 2024 findings reported that the mission attributed her death to physical violence and found crimes against humanity in the response to protests. These are attributed investigative findings, rather than a claim that every allegation has received a judicial determination. s4

President Ebrahim Raisi’s death in a helicopter crash in May 2024 prompted an early election, won by Masoud Pezeshkian. Human Rights Watch’s account of that year also documented continuing arrests and restrictions affecting activists, students, and relatives of people killed during the 2022 protests. A change in the presidency therefore needs to be assessed alongside evidence about the conduct of other institutions. s5

For 2025, Human Rights Watch described continued persecution of women, minorities, and perceived dissidents. It also reported that the June conflict with Israel was followed by intensified domestic repression justified in the language of national security. This is the organization’s documented assessment; it should not be replaced by an assumption that external conflict suspends domestic political tensions. s6

The historical account must extend beyond the leadership arrangements familiar from earlier decades. In a report dated 20 March 2026, Associated Press described Ali Khamenei’s death in the opening attacks of the war and the naming of his son Mojtaba as his successor. Its reporting distinguished the successor’s formal position from uncertainty over operational control, including analysts’ assessments of the Revolutionary Guard’s influence. This is a dated account, not verification of the leadership situation in October. s7

Separately, the Center for Human Rights in Iran’s September account of the UN fact-finding mission’s latest report described widespread killings, detention, torture, and communications restrictions during the suppression of protests that began in December 2025. It reported the mission’s conclusion that numerous violations amounted to crimes against humanity. The underlying UN report could not be retrieved in this research session; these findings are therefore presented through the inspected secondary account. s8

Taken together, the evidence supports reading post-revolutionary politics through both institutions and contested participation. A complete history still requires fuller coverage of the intervening decades and verification of developments through the editorial cutoff.
